3 Claims. (Cl. 20-42) This invention relates to a window construction and more particularly to a window sash which is movable inwardly, away from its sealing position, and then slid horizontally to an open position.

An object of the invention is to provid-e a torque rod, at the side of the window sash, which actuates to move the sash inwardly into engagement with a slide bar whereby it may be moved to an open position.

Another object of the invention is to provide a pair of torque rods at the opposite sides of the sash which act as parallelogram in moving and guiding the sash during the opening and closing operation.

A further object of the invention is to provide a window construction in which a movable window sash is sealed in its closed position.

Other objects and advantages of lthe invention will more fully appear from the following description taken in connection with the accompanying drawing in which:

Fig. 1 is a horizontal sectional view of a window showing Ian adaptation of the invention;

Fig. 2 is an enlarged view showing the slide bar and operating handle, in the closed position;

Fig. 3 is a view corresponding to Fig. 2 showing the slide bar and handle in a position for drawing the window sash inwardly; and

Fig. 4 is a longitudinal sectional view showing the window sash in its closed position.

Fig. 5 is a view, partly vin section, of the left hand torque rod and its attached elements.

Referring to the drawing, we have shown a window frame which is mounted in the side wall of a building. A sash 12 is mounted in a portion of the frame 10 and a movable sash 14 is mounted in another portion of the frame 10 for sliding movement wi-th respect to the sash 12 and the frame 10. A screen 16 is provided in that portion of the frame 10 which receives the movable window sash 14.

The frame 10 is provided with a exible ange 18, surrounding the opening receiving the movable sash 14, for tightly sealing the opening when the sash is in the closed position.

The movable windowsash 14 comprises a frame 20 having an outwardly extending flange 22 which is adapted to contact the exible ange 18 when the window sash is closed. The frame 20 supports the window panes 24, which may be of the dual type.

The sill 26 of the window frame 10 is provided with a sash supporting section at one side thereof and a slide supporting section having a track 28, in Ithe form of a groove, in its upper surface extending longitudinally thereof and laterally spaced from the sash supporting section. A slide member 30 is received in 'the slide supporting section which carries the track 28. The track 28 has laterally extending grooves 32 extending under the window sash 14 into the sash supporting section. A similar track 34 is provided at the top of the window and it is provided with a slide member 36; the track 34 having lateral grooves 38. Pivotally mounted on the .Patented Apta-'530, 1957- slide members 30 and'36. are links 40 provided with pins 42 and 44. The pins 42are received in the slide members 30 and 36 and the pins 44 are receivedin the grooves 32 Iand 38. V

At the'opposite sidesof the window sash14, and in the frame thereof, are torque rods 46 which are connected to the upper and lower pins 44. One of the links 46, preferably the lower left,"is provided with a handle 48. A pull on the handle causes the link 40 to be pivoted about the pin 42 and withdraws the pin 44 out of the groove 32, in the sash supporting section, into the path of the slide bar 30, in the slide supporting section, there being a notch 50 in the slide bar for the reception of the pin. The movement of the slide bar 30 causes the links 'at the opposite side of the sash to be pivoted about their respective pins 42, drawing the window sash forwardly away from ithe frame 10 and the resilient sealing flange 18, after which the window sash may be slid transversely past the stationary sash 12.

The lower edge of the window frame 10 is provided with a shoe 52 which rests on the sill 26 and is free for sliding movement therewith.

The invention has been illustrated and described in a window sash which is adapted to be moved horizontally for opening and closing, but it is equally adapted to sash which move vertically. If it is desired to move the sash vertically, the slide members are arranged at the sides of the sash and the torque rods are located above and below the sash.

While the inven-tion has been illustrated and described in connection with a specific embodiment thereof, it will be understood that various changes, including the size, shape and arrangement of parts, may be made without departing from the spirit thereof and it is not our intention to limit its scope other than by the terms of the appended claims.

I claim:

1. In `a window construction, a frame having a sash supporting section in one plane thereof and a slide supporting section in another plane thereof and spaced from said sash supporting section, a sash normally in said sash supporting section, torque rods carried by said sash, one at each of the opposite side edges of said sash, said rods being guided in grooves in said frame which extend from said sash supporting section` to said slide supporting section, a sliding member carried by said slide supporting section, a handle pivoted to said sliding member and connected to one end of one of said rods, and a link forming a connection between the other of said rods andl said sliding member, whereby when said handle is pivoted about its pivotal connection to said sliding member said rods and sash are moved from the sash supporting section into the slide supportingv section to be bodily moved into the path of and carried by said sliding member.

2. In a window construction, a frame having a sash supporting section and a slide supporting section in a plane spaced from the plane of the sash supporting section, a sash normally in said sash supporting section, sliding members carried by said slide supporting section, torque rods carried by the opposite side edges of said sash and projecting above and below said sash, links forming a pivotal connection between the opposite ends of said rods and said sliding members, and a handle connected to one of said links for moving one of said slide members thereby causing pivotal movement of said links to draw said sash bodily into the path of said sliding member.

3. In a window construction, a frame having a sash supporting section eand ya slide supporting section in a plane spaced forwardly from said sash. supporting section, a sash normally in said sash supporting section, a

sliding memberffin said slide supporting section, links forming a pivotal connection between said sash and said sliding member, and a handle connected to one of said links for drawing said sash out of said sash supporting section `whenl said link is pivoted by the handle into theY path of said sliding member and moving said sliding member.
